Amavalvu ovemvane asetshenziswe kakhulu iminyaka eminingana kumaphrojekthi amaningi emhlabeni wonke futhi afakazela amandla awo ekwenzeni umsebenzi wawo ngoba awabizi futhi kulula ukuwafaka uma kuqhathaniswa nezinye izinhlobo zamavalvu okuhlukanisa (isib. amavalvu esango).
Izinhlobo ezintathu ezivame ukusetshenziswa ngokuphathelene nokufakwa yilezi: Uhlobo lwe-Lug, uhlobo lwe-Wafer kanye ne-flanged kabili.
Uhlobo lwe-Lug lunezimbobo zalo ezithenjiwe (intambo yesifazane) evumela ukuthi amabhawodi afakwe kuwo ezinhlangothini zombili.
Lokhu kuvumela ukudilizwa kwanoma yiluphi uhlangothi lwesistimu yamapayipi ngaphandle kokususwa kwe-valve uvemvane ngaphezu kokugcina isevisi ngakolunye uhlangothi.
Kubalulekile futhi ukuqaphela ukuthi awudingi ukuvala lonke uhlelo ukuze uhlanze, uhlole, ulungise, noma ushintshe i-valve butterfly ye-lug (kuzodingeka uvale nge-valve yebhotela le-wafer).
Okunye ukucaciswa nokufakwa akucabangi le mfuneko ikakhulukazi ezindaweni ezibucayi njengokuxhumeka kwamaphampu.
Amavalvu ovemvane anezinhlangothi ezimbili angaba yinketho ikakhulukazi ngamapayipi amakhulu obubanzi (isibonelo ngezansi sibonisa amapayipi angu-64 ku-Diameter).
Iseluleko sami:Hlola ukucaciswa kwakho nokufakwa kwakho ukuze uqinisekise ukuthi uhlobo lwe-wafer alufakiwe ezindaweni ezibucayi kulayini ezingase zidinge noma yiluphi uhlobo lokunakekelwa noma ukulungiswa phakathi nempilo yesevisi esikhundleni salokho, sebenzisa uhlobo lwe-lug ohlwini lwethu lwamapayipi ezinsizeni zokwakha. industry.Uma unezinhlelo zokusebenza ezinobubanzi obukhulu, ungase ucabange ngohlobo oluphindwe kabili.
